COMBINED RAJJIQ AND PHONOGRAPH CABINET CONSTRUC'I'XQN.

Application filed January 26, 1924. Serial Ho. 688,769.

' To all whom it may concern:

Be it known that I, Mourns Srnrrnnn, a citizen of the {United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Qombined Radio and Phonograph Cabinet Construction of which the-following is a full, clear. and exact des ription.

The invention relates to a new and iniproved cabinet combining a phonograph and a radio apparatus, and has for an object the provision of a simple and efiicient means whereby a common horn can be used to J. sounds or radio broadcasting.

Another object concerns the provision of a simple andeflicient construction whereby by the simple manipulation of a single element the ordinary phonograph horn can be connected alternately to a radio loud speaker or to the phonograph tone arm.

The invention is illustrated in the drawings, of which Figure 1 is a plan view of the cabinet;

Fig. 2 is a section taken on the line 2-42 of Fig. 1;

Fig. 3 is a section taken on the line 83 of Fig. 2; and

Fig. 4 is a section taken on the line 4- of Fig. 2.

The form of the invention shown the drawings is a preferred form, although it is understood that modifications in the construction and arrangement of the parts and in the character of the materials used may transmit either phonop'rnphically produced be adopted without departing from the spirit of the invention as set forth in the appended claims.

In the commercial application of radio to-da'y it'is common practice to combine a radio apparatus witha phonograph appa'-.

ratus 'in the same cabinet and to utilize the same horn for both reproductions. In order to simplify the construction and mechanismnects directly with aphonograph horn (n ot shown) and ordinarily extends u w ardly I from beneath the platform 2 on the nonograph, through the aperture 3 therein above and in registration with which there disposed the usual tone arm 4. The body portion 5 which contains the main sound passage 1 is laterally apertnred, as shown at 6, to connect with an auxiliary body portion containing an auxiliary sound passage '8 in the end of which a radio loud speaker device or amplifier 9 canbe disposed.

It will, therefore, be seen that as thus far described the invention includes the associ ation of a main sound passage 1 with the two auxiliary passages, namely, the passage 8 and the passage 10, formed within the tone arm 4. It is obvious that when sound is a being transmitted from one of these auxiliary passages into the main passage to be transmittd through the phonograph horn it is not desirable to have the other auxiliary passage connected with the main sound pas sage. To this end, I provide a air of slid-- able members 11 and 12 in the orns of slidable plates which move in suitabie slots formed in association with the body portions 5 and '2', and by cason of their (iiSPOStiCIi are disposed to be interposed respectively between the main sound passage 1 and the auxiliary sound passages 10 andv The slidable member 11 is provided with anaperture 13, and the slidable member 153 is provided with an aperture 14, so that in one position of the slidable members" their aperposed that theywill not both bein registra-' tion with their respective sound passages at the sameftime.

As shown in Fig. 3, the slidable members 11 and 12 are connected at their ends to an operating plate 15 to which an arm 16 is connected, this arn'i extending forwardly through'the slot 17 in the table or platform Q'and provided on its upper end Witi-rlznoh 18 whereby the arm canbe manipulated slide back and forth in the slot? 17 and through this action to move the plates .11

and12f In the position shown the dfi'faw wit its ings, the member 11 is dispo aperture 13 in alignment between themain sound passageil and the auxiliary sound passage 10 in the tone arm 4, whereas the member 12 is disposed with its out off alignment between the mtun passage 1 and the auxiliary passage 8. Inthis position, therefore, the horn reconnected to the phonograph tone arm, whereas itis obvious hperturo 14 that if the knob 18 ismoyedto the other end '1 of the Slot 17 the connection between the main sound passage 1 and the auxiliary passage will be interrupted and the connection between the main sound passage '1 and the auxiliary passage 8 will be established a through the aperture 1 so that the phono- 9. Fh-is apparatus,

i in, a plurality of other body portions havgraph horn can be used to transmit sound produced by the radio loud speaker device excepting for the knob 18, is disposed beneath the plaform or table 2 and is hidden from View. The only visible part of the apparatus is the knob 18 by means of which the slidable plates are operated after they have been assembled. Their movement is e-fi'ected by the simple sliding back and forth of the ,knob 18 to effect the registration desired.

It is desirable to provide the opposite surface of the slidablc members With material 19, such as felt, whereby the sliding engagement between the sides of the slidable memhers and the walls of the body portions through which they pass may be made as snug as possible to eliminate the leakage of sound therethrough and to prevent the movement of the plate from being too free.

-What I claim is 1- 1. A combined radio and phonograph cabinet construction, which comprises a body portion having a main sound passage theregcs therein conassage, slidable 3 body portions ing auxiliary sound passa nected to the main sound apertured members in sai adapted to be interposed between the main 85 passage and the auxiliary passages, and means for moving said slidable members simultaneousl to alteri iately register their respective ape jtures between the main sound passage and {the respective auxiliary pa s- 40 sages whereby the flow of sound between the main passage and the auxiliary passages can be selectively controlled.

2. A combined radio and phonograph cabinet construction, which comprises a'body portion having a main sound passage, a body portion ha-vin an auxiliary sound passage to which a phonograph tone arm is connected, a second-auxiliary body portion hav-,

ing a sound passage therein to which a radio loud speaker device can be attached, a slidable plate in each of said body portions to be interposed between the main sound passage and the respective auxiliary passages, each of said plates being aperturcd, and means fora- MORRIS STETTNER.
